PURPOSE: The escaping guidance indication board of a tunnel escaping connection path is provided to improve durability by minimizing influence by wind which is induced by atmospheric pressure difference of the inside and outside of a tunnel and improving the strength of a board. CONSTITUTION: A sealing member(60) comprises a waterproof member(61), an insertion part(63), and a correspondence insertion part(65). The waterproof member is connected to the inner side of a frame(31). The insertion part is formed in the inner side, the outer side, or the boundary surface of the waterproof member. The correspondence insertion part is formed in the edge part of a main body and corresponds to the insertion part. One side or both sides of the main body is opened. A mounting part is included in the main body and an emitting means is combined to the mounting part. An opening and closing door which includes a non-protrusion type light transmitting member is connected to the frame.
